The driver who ploughed into football fans during Liverpool's trophy parade 'tailgated' an ambulance to access the 'closed' road where the horror smash unfolded, MailOnline understands.

Police are today facing major questions over how the people carrier accessed Water Street, a packed road in the city centre, before it rammed into a huge crowd at around 6pm on Bank Holiday Monday.

Liverpool City Metro Mayor Steve Rotheram said the 'big question' was how the Ford Galaxy ended up among the crowds, adding: 'Water Street was not a route where vehicles were supposed to be using it, it was blocked off.'

A source has now told the Mail that there were bollards at the top of the road, at the junction of Dale Street close to the Town Hall, but these were moved to allow an ambulance to get through and the driver 'tailgated' it to access Water Street.

Another witness, who was forced to jump out the way of the oncoming vehicle, said the driver 'navigated' past a 'road closed' sign.
